I did a conversion because my "accountant" would definitely notice a $600 transaction (like if I bought a new bike) but she has trouble keeping track of lots of smaller ones (saddles, seat posts, stems, chains, cogs etc) especially when I skim money out of what I can get from the ATM every week or so.

Otherwise I'd be riding a new IRO right now rather than my (now totally cool, hand built and painted by first graders) conversion.
